The internet lost its collective mind late yesterday when Justin Bieber uploaded a photo on his Instagram account showing him holding up what appeared to be a personalized script for the "Batman vs. Superman" film at Warner Bros.

He captioned said picture "#Robin". Cue wild screaming of all kinds of varieties, and more than a few wondering what the truth was behind the photo - a casting announcement or a practical joke.

A source tells Hollywoodlife that it's the latter - "Justin Bieber will NOT be in the next Batman film, either as Robin or craft services."

More telling is that Bieber shot a skit for Funny Or Die that day, which means it's almost certainly a prop from that video.
